I thought the Fair Use policy stated in the copyright law is pretty clear.
Here it is - section 107 (I have it bookmarked

)
§ 107. Limitations on exclusive rights: Fair use
Notwithstanding the provisions of sections 106 and 106A, the fair use of a copyrighted work, including such use by reproduction in copies or phonorecords or by any other means specified by that section, for purposes such as criticism, comment, news reporting, teaching (including multiple copies for classroom use), scholarship, or research, is not an infringement of copyright. In determining whether the use made of a work in any particular case is a fair use the factors to be considered shall include —
(1) the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes;
(2) the nature of the copyrighted work;
(3) the amount and substantiality of the portion used in relation to the copyrighted work as a whole; and
(4) the effect of the use upon the potential market for or value of the copyrighted work.
The fact that a work is unpublished shall not itself bar a finding of fair use if such finding is made upon consideration of all the above factors.

Not nebulous? It is a series of guidlines for determining on a case by case basis, not a solid 'thou shalt not', in comparison to the rest of the code it is quite nebulous. The apparent ambiguity of sections (1), (3), and (4) are what is commonly used by websites to cover their as... umm, I mean justify the use of copyrighted material. Fun also creeps in because of differences in domestic and international copyright laws. (Which resulted in the Ace Books 'pirate edition' of The Lord of the Rings in the 1960s.)
Sorry about that, I actually enjoy arguing this.

And if you throw in legal precedents then it goes all over the place! The court has flip flopped more often than rubber sandles at the beach.
